Specification of Letters Patent.

Patented'Mar. 4,1919.

Application filed December 5, 1917. Serial No. 205,638.

To all whom t may concern:

Be it known that I, JosErHINE L. TABOUR, a citizen of the United States, residing at Englewood, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in J ar-Cap Handles, of which the following is a specification.

This invention relates to improvements in preserving jars, more particularly to jars having screw tops or covers and commonly known as the Mason screw top jar, and has for one of its objects to provide attachments whereby the application to or the reino-val of the screw cap from the jar is expedited, and the force of the compression of the cap against the yieldable packing materially increased.

Another object of the invention is to provide a device which may be adapted without material structural change to jars of varying sizes.

Another object of the invention is to provide a device of this character which will reinforce and strengthen the screw cap without materially increasing the weight or expense of construction.

Vith these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention- Figure 1 is a plan view, partly in section, of a jar cap with the improvement applied.

Fig. 2 is a side elevation, partly in section of the parts shown in Fig. 1.

Two of the improved devices will be em'- ployed upon each jar cap, preferably at its diametrically opposite sides, but as the attachments are precisely alike the description of one will suiice for both.

The attachments each comprise a body portion 10 preferably extended into a finger loop or eye 11 at the outer end and with laterally directed extensions 12-13 at the inner end. The inner edge of the body 10 and its extensions 12-13 are concaved or inwardly curved to correspond to the curvature of the jar or closure. The cap or closure is represented as a whole at 14, and

' includes the screw threads 15 which are formed integrally with the cap by spinning or pressing in the usual manner. The concaved or curved edges of the attachment are preferably engaged between a pair of the threads 15, as illustrated in Fig. 2, and soldered or otherwise rigidly attached to the cap.

By this means efficient handle devices are provided whereby the labor incident to the attachment or removal of the cap is materially decreased. By this means also a very strong leverage action is provided which is of great advantage in overcoming the adhesion of the packing to the jar, especially if the contentsy of the jar has hardened the packing or caused it to stick upon the glass or the metal of the cap.

By extending the bearing surfaces of the.

attachments by means of the' extensions 12-13 the relatively thin metal of the cap 14 is reinforced and strengthened, and all tendency to fracture or distortion is resisted, and the strength of the cap materially increased without material increase in expense or weight.

The attachments will be preferably constructed of noncorrosive metal, or galvanized, or otherwise treated to prevent ferent elevations, said handles being provided with laterallyA extending arms conforming to and fitting within the adjacent threads on the rim.'

2. The combination with a container closure having a depending externally and internally threaded rim, of oppositely disposed coacting handles each comprising a body portion having a finger opening therein and provided with laterally extending arms conforming to and fitting within the adjacent threads on the rim and rigidly secured to said rim, said handles being disposed at different elevations and arranged in the plane of the adjacent threads.

In testimony whereof I afx my signature.
